Ideally items like an iPhone or an Xbox one x thanks for the reply.

if its your first time SE'ing i would highly suggest you dont go for pricey items such as iphones because you may need alot of experience going into that . My first SE was for £30 for a bunch  of vitamins from amazon work your way up

do you have method tutorials

If I may comment, food/consumable Items are the easiest to SE, a method Is not needed.

Simply Issuing a complaint of feeling "extremely sick" Immediately after eating/drinking It, Is almost guaranteed to work.
